Abstract: A spectrometer and method of spectroscopic analysis for providing spectral data concerning a scene by collecting and collimating radiation from the scene to provide a radiation beam dispersing the radiation of the beam into a spectrum, forming a focused image of the spectrum, scanning the spectrum image in rapid succession by multiple narrow radiation receiving areas, and generating an electrical output representing the radiant flux incident on each area during its relative scanning movement along the image. The spectrometer may be equipped with means for mounting radiation filters over selected radiation receiving areas to provide information concerning selected characteristics, such as relative polarization, of the radiation from the spectrum image and for mounting narrow band-pass calibration filters over alternate radiation receiving area to permit calibration of the spectral data obtained from the scene.

Abstract: Disclosed is an improved polarimeter and polarimetric method. The heart of the polarimeter is a Faraday rod within a concentric coil. The light being analyzed is imaged at a field stop, passed through the rod and, subsequently, through an analyzer. Electric current pulsed through the coil according to a prescribed waveform creates a pulsed magnetic field within the rod, causing the plane of polarization of the incoming light to rotate by an amount varying according to the particular current waveform. This, in turn, creates a varying degree of attenuation, by the analyzer, of the plane polarized component of the light. Means are provided for measuring this variation of attenuation, by which measurement the degree and angle of polarization of the incoming light may be determined, as well as the intensity thereof.
